Fig. 5. (Top) Schematic of the reduction of MIL-125 with 
. The darkening indicates addition of electrons, and incorporation of sodium is designated by the red Na+. (Bottom) Extent of MIL-125 reduction versus equiv. of Na+ added to various batches of MIL-125. Experiments with 2 (circles) and 10 (squares) equiv. of 
are plotted. The dashed line represents a 1 : 1 stoichiometry, and is not a fit. Description of the MIL-125 crystallites are: batch 1 has ellipsoid morphology and axes of 300 (±100)–850 (±50) nm; batch 2 has spherical morphology with axes of 85 (±17) nm; batch 3 has octahedral morphology with edges of 2650 (±1350) nm; batch 4 contains deuterated bdc linkers and has ellipsoid morphology and axes of 600 (±200)–1150 (±350) nm.
